President Donald Trump and German Chancellor Angela Merkel make remarks together at the NATO Artifacts Ceremony in Brussels, Belgium.

In the past, Trump has disparaged NATO by calling it obsolete and saying that they don’t do enough to fund the military alliance and international security. Trump reversed last month and said the organization is “no longer obsolete,” though he might use today’s meetings to pressure member nations to contribute more funding.

Trump’s visit to NATO HQ will be his first opportunity to directly engage with several world leaders who are also part of the European Union.
